Description

Technical Field

[0001] The utility model relates to the technical field of magnetic field measurement tools, in particular to a patch type magnetic field measurement device. Background Art

[0002] Magnetic field measurement includes the measurement of various magnetic fields such as the earth's magnetic field, DC magnetic field, AC magnetic field, radiation magnetic field, acoustic device, magnetic separator, and the working magnetic field of permanent magnets. Magnetic field measurement is of great significance in the fields of scientific research, experiment, production and life. For example, the measurement of the earth's magnetic field plays an important role in guiding, prospecting, geomagnetic power generation, predicting natural disasters, explaining natural phenomena, and military and industrial fields. Traditional geomagnetic field measurement instruments can usually only measure the direction of the geomagnetic field, such as a compass, which can measure the direction of the magnetic field but cannot measure the intensity of the magnetic field. The existing magnetic field measurement equipment sensor probe is usually connected to a signal line by the sensor probe body, and there is no way to fix it. When measuring the magnetic field, the sensor probe is fixed by hand-held method. The hand-held method is suitable for inspection. The test is fast, but there will be slight jitter and certain skills need to be mastered. In addition, when accurately measuring, the measurement personnel need to keep a posture for a long time without moving, which is difficult and easy to cause rigid fatigue. In addition, the outer wall of the main structure to be measured usually has different shapes. The fixing method of using ropes or tapes to tie the outer wall needs to be targeted according to the actual shape of the outer wall of the structure, and the operation efficiency is low.

The volume of the airbag 302 is slightly smaller than the volume of the cavity in which it is located. The airbag 302 can cooperate with the mounting pad 301 with a certain elasticity to make as many comb teeth 3011 as possible contact the outer wall of the measuring main structure, thereby making the patch body 1 more closely fit the outer wall of the measuring main structure and restoring the mounting pad 301 and the comb teeth 3011 to their initial positions after the measurement work is completed.

[0034] Preferably, in this embodiment, the comb teeth 3011 are evenly arranged and installed on the surface of the installation pad 301.

After the patch body 3 is placed in the storage bin, it and the device body 1 form a more compact overall structure, which is convenient for sorting and transportation.

[0037] Preferably, in this embodiment, an Internet of Things microcontroller 101 is installed inside the device body 1.

[0038] Preferably, in this embodiment, a wireless communication module 102 is installed inside the shell of the device body 1, and a SIM card 1021 is installed in the wireless communication module.

[0042] When the utility model is in use, the latch bolt 106 on the device body 1 is pulled away from the device body 1, the patch body 3 is taken out from the storage bin 105 in the device body 1, and placed on the structural outer wall of the measuring body, the patch body 3 is pressed downward, so that the comb teeth 3011 in the patch body 3 are abutted against the structural outer wall of the measuring body under the joint action of the airbag 302 and the mounting pad 301, and the patch body 3 is pressed downward again. After a simple adjustment, the patch body 3 is stably attached to the structural outer wall of the measuring body, and then the corresponding measurement switch on the device body 1 is turned on to perform magnetic field measurement.
